Don’t think Holley is just “old-school” fuel systems either. Its latest fuel pumps are these super-trick billet electric in-line pumps. Shown here is the HP pump, which can handle 700 EFI horsepower, or up to 900 horsepower if you still have a carb. Holley’s Dominator series houses two pumps that can be run simultaneously, or one for the engine and one on demand for the supercharger.
